摘要
图像超分辨率是指从一序列低分辨率观测图像中重建高分辨率图像。图像超分辨率充分利用了各帧图像间相似而又不同的信息。该技术可以广泛应用于遥感、医学成像和高清晰度电视等多个领域。回顾了经典超分辨率算法,介绍了目前超分辨率算法及其扩展研究方向的一些最新进展,指出了图像超分辨率有待进一步研究的几个可能的方向。
Super-resolution reconstruction is a technique for reconstructing a high-resolution image (or sequence) from an image sequence of low-resolution observation. Super-resolution makes full use of the similar but not the same information among each observation. This technique is widely used for remote-sensing, medical imaging and high-definition television (HDTV) standard, etc. The classic methods of super-resolution are described, especially the newest development in super-resolution algorithm and the expanded field recently. The possible directions of future research are proposed.
